线渲染器和子弹的射击方向不一样

Question

我正在实现我的第一个第三人称游戏。在这个游戏中，我想朝鼠标的方向射击。因此，我从相机向地面投射光线。为了让射击效果更好，我从玩家到当前鼠标位置画了一条线（见截图）。

如果玩家按下开火按钮，应该会产生一颗子弹并朝线条渲染器的方向射击。

不幸的是，子弹没有飞向鼠标的方向，我不确定为什么？

两个脚本：线渲染器和子弹生成和射击都在同一个游戏对象上。

当前代码

线条渲染器：

void Update()
{
    Vector3 pos = new Vector3(200, 200, 0);
    Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
    RaycastHit hit;
    

    if (Physics.Raycast(ray, out hit, 100)) 
    {


        linePointing = new Vector3(hit.point.x, hit.point.y, hit.point.z); // really unnecessary but I want the line Pointing as my hit point

        linePointing.y = gameObject.transform.position.y;
        Vector3 localCord = gameObject.transform.InverseTransformPoint(linePointing);



        float angle = Mathf.Atan(localCord.x / localCord.z) * Mathf.Rad2Deg;

        //This is just so the player cant shoot in every direction
        if (Mathf.Abs(angle) < 80 && localCord.z > 0)
        {
            m_lineRenderer.SetPosition(1, localCord);
            m_lineRenderer.SetPosition(2, localCord * 100);
        }


    }

}

子弹生成（也在更新中）

    GameObject bullet = Instantiate(bulletPrefab);
    bullet.transform.parent = gameObject.transform.parent;

    Physics.IgnoreCollision(bullet.GetComponent<Collider>(), bulletSpawn.parent.GetComponent<Collider>());

    bullet.transform.position = bulletSpawn.position;

    Vector3 rotation = bullet.transform.rotation.eulerAngles;

    bullet.transform.rotation = Quaternion.Euler(rotation.x, transform.eulerAngles.y, rotation.z);
    bullet.GetComponent<Rigidbody>().AddForce(getShootingDirection().normalized * bulletSpeed, ForceMode.Impulse);

    //Change parent, so the player movement doesnt affect the bullet
    bullet.transform.parent = null;

获取射击方向-方法 此方法与线渲染器相同，但我想将其分开

 private Vector3 getShootingDirection()
{
    Vector3 linePointing = Vector3.zero;
    Vector3 localCord = Vector3.zero;
    Vector3 pos = new Vector3(200, 200, 0);
    Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
    RaycastHit hit;

    if (Physics.Raycast(ray, out hit, 100))
    {
        linePointing = new Vector3(hit.point.x, hit.point.y, hit.point.z)
        {
            y = hit.point.y + 0.5f
        };

        localCord = gameObject.transform.InverseTransformPoint(linePointing);


    }
    return localCord;

}

RigidbodyAddforce 在世界坐标中添加了一个力，我认为你是在局部坐标中添加了一个力。你可以看看。

线渲染器和子弹的射击方向不一样

Shooting direction isnt the same between line renderer and bullet
